This article presents the use of remote experimentation laboratories and its application in the school context. The purpose of this educational tool is to complement the teaching and learning process and to promote learning beyond the classroom through the use of technology. Remote experimentation has been configured as an alternative to promote this learning supplement thus helping the new generation...
Online laboratories are currently widely used in several educational settings, including lectures, individual or small group assignments, inquiry activities, homework and even hands-on laboratories. Usually they are proposed by teachers as additional and complementary resources, not included into the curricular activities. Moreover, for many teachers it is not clear if they are synergic to the school's...
This paper was aimed to study the thin-layer drying of osmotic dehydration of Thai cherry tomato (Queen cherry tomato) and to investigate the thin-layer drying kinetics of osmotic dehydration of cherry tomato by using a convective air dryer. The osmotic dehydration of cherry tomato was dried under controlled conditions of temperature of 50°C, 60°C and 70°C and relative humidity (rh) of the drying...
Low Earth Orbit (LEO) is becoming increasingly populated by orbital debris of all sizes and shapes that is hazardous to operational spacecraft. NASA has recently determined that a collision with debris between 0.5 mm and a few centimeters would be “mission ending”. Recently, a novel technique to remediate small debris (less than 10 cm) from Low Earth Orbit (600 – 1100 km) has been proposed that uses...
Programs of scientific research, like other formally organized collective practices, meet the materiality of the world in complex and dynamic ways. This intersection has important and under explored consequences for the planning and practice of distributed scientific collaboration, including programs of large-scale infrastructure development currently underway across a range of scientific fields and...
We demonstrate a nanophotonic platform based on 2D materials coupled to photonic crystal cavities. We show strong enhancement (∼60 times) of light emission due to the photonic crystal.
Project based learning (PBL) has become more popular due to its student centered nature of learning compared to traditional modes of learning. However, it is not always feasible to implement it due to several reasons. At the University of New South Wales, the PBL mode was trialled on an introductory Digital Signal Processing course for two consecutive years and the evaluation was previously reported...
This paper presents a blended learning model that has been successfully developed and applied at the College of Computing and Business Communications eMPIRICA in BiH, in frame of the study program Engineering Informatics. A developed and implemented blended learning model was created along the lines of Flex model, where the content, instruction and continuous assessment are delivered to students by...
In the last 10 years we have provided an interactive online course on Computer Architecture and Organization, which uses Online Learning and Interactive e-Assessment technology to support easier learning. The technology enabled an interactive environment which, checks student's knowledge and enables continuation to the next learning environment based on decision making criteria to check if sufficient...
In marine archaeology, many artifacts made of metallic or organic material are found in different state of conservation depending of the environment in which they are discovered. Once brought to the surface for study or display purposes, the artifacts need to be treated properly otherwise they deteriorate in a short lapse of time. The fragility of organic artifacts and the volumetric variation caused...
Development of the educational technology in field of the engineer's training have received great attention in recent years. The new information technology will significantly improve the methods of technical discipline teaching and thus level of the engineering students. This paper describes the results of IT using for virtual course creation and presents the structure of multimedia laboratory course...
The introductory continuous-time signals and systems (CTSS) course is widely considered to be one of the most difficult courses in electrical and computer engineering (ECE) curricula. This interactive workshop explores the sources of difficulty and presents some approaches to help improve learning and understanding. It will begin with a discussion about learning difficulties that are identified by...
This paper details the changes undertaken to the introductory Bachelor of Engineering (BE) course Foundations of Engineering (ENGR101) at Victoria University, Wellington, New Zealand (VUW) to improve first year student engineering experience. A requirement of the BE is that a student obtains a B average over their core papers in Part I to progress with the degree. The paper also reports on student...
Simultaneous reduction of graphene oxide (GO) and silver nitrate (AgNO3) into stabilizer-free Ag-Graphene Naoncomposite (AGN) using DMAc-assisted thermal reduction method with controllable density of Ag nanoparticles (Ag NPs) is reported. Microscopy techniques (scanning electron microscopy and high-resolution transmission electron microscopy) have been employed to probe the morphological characteristics...
Material interfaces often reveal complicated and interesting phenomena and physics during electrical breakdown. In this talk, the physics at interfaces in two specific applications will be discussed. One involves the insulator-electrode interface of photoconductive semiconductor switch (PCSS) devices. Another is the air-dielectric interface found in many electrical breakdown phenomena, such as lightning...
Wire array z-pinches on the Z generator are bright sources of radiation from 200eV to 9keV. Typically, wire materials are varied to provide emission in a specific spectral band, and the array setup is varied in order to provide appropriate energy per ion to heat the stagnated plasma to an electron temperature conducive to efficient emission within that band. Here we discuss a series of experiments...
The DARHT-II accelerator produces a 2-kA, 17-MeV beam in a 1600-ns pulse. After exiting the accelerator, the pulse is sliced into four short pulses by a kicker and quadrupole septum and then transported for several meters to a high Z material target for conversion to x-rays for radiography. The un-kicked beam is diverted to a graphite dump. The interaction of this beam with the dump produces ions...
A life cycle costing (LCC) is to be performed complementary to the ongoing research on an enhanced supercapacitor pouch cell, in order to provide additional decision support on the best cell chemistry from the economic point of view. Due to the early stage of the project so far merely the production phase is considered. The detailed cost calculation method was chosen and complemented with a scale...
6.002x is the first electronic circuits course to be taught online to tens of thousands of students. The goal of the 6.002x experiment was to explore ways to use computerassisted instruction to surpass the quality of traditional residential teaching. By providing superior on-line content delivery and assessment, we hope to both be able to educate people without access to education, and to improve...
